Abstract

An improved surgical appliance suitable for temporary gastrostomy for humans is provided in the form of an elongated, multiple lumen gastrostomy tube, which is adapted to provide both (1) gastrointestinal decompression by means of suction, thereby significantly removing both undesired swallowed air from the stomach and excess collections of gastric fluids from pools formed in the stomach, while simultaneously, substantially equalizing pressure in the stomach by use of venting means, and (2) intraduodenal or jejunal feeding by intubation and infusion.

Claims

1. A multiple lumen elastomeric gastrostomy tube, said tube having a distal end portion adapted to be surgically inserted into a patient'"'"'s stomach, a proximal end portion adapted to remain outside the patient'"'"'s body, and an intragastric balloon portion for retaining said tube in the patient'"'"'s stomach;

a first longitudinally-extending decompression lumen in said gastrostomy tube, said decompression lumen having an open, proximal end-portion adapted to be connected to a suction means, a closed distal leading end portion, and a plurality of communicating aspiration apertures along said tube distal end portion, whereby the fluid contents of the stomach may be evacuated through said decompression lumen in response to suction;

a second elongated venting lumen in said gastrostomy tube, said venting lumen having an external opening on said gastrostomy tube proximal end-portion, and an intragastric opening on said tube distal end-portion, said venting lumen adapted to allow atmospheric air to flow into the stomach in response to pressure differentials resulting from suction;

a third inflation-deflation lumen having a distal end communicating with said intragastric balloon portion, and a proximal end adapted both to communicate with a source of balloon inflation fluid and to retain said fluid in said balloon, and, thereafter, to provide means for egress of said fluid during removal of said gastrostomy tube;

a fourth substantially elongated feeding lumen in said gastrostomy tube, said feeding lumen having inlet and outlet openings positioned at proximal and distal portions, respectively, of said gastrostomy tube, said feeding lumen constructed to receive an intraduodenal feeding tube inserted therethrough; and

annular elastomeric sleeve means affixed to said gastrostomy tube, in trailing relationship to said intragastric balloon portion, said annular elastomeric sleeve means adapted to contact the abdominal walls where said gastrostomy tube is surgically inserted, and said sleeve constructed of material which induces the formation by the patient'"'"'s body of a protective fibrotic sheath in the area of said contact.

3. Apparatus according to claims 1 or 2 wherein said elastomeric sleeve is formed from rubber latex.

2. A surgical device, comprising:

(A) A multiple lumen elastomeric gastrostomy tube, said tube having a distal end portion adapted to be surgically inserted into a patient'"'"'s stomach, a proximal end portion adapted to remain outside the patient'"'"'s body, and an intragastric balloon portion for retaining said tube in the patient'"'"'s stomach;

(i) a longitudinally-extending decompression lumen in said gastrostomy tube, said decompression lumen having an open, proximal end-portion adapted to be connected to a suction means, a closed distal leading end portion, and a plurality of communicating aspiration apertures along said tube distal end portion, whereby the fluid contents of the stomach may be evacuated through said decompression lumen in response to suction;

(ii) an elongated venting lumen in said gastrostomy tube, said venting lumen having an external opening on said gastrostomy tube proximal end-portion, and an intragastric opening on said tube distal end-portion, said venting lumen adapted to allow atmospheric air to flow into the stomach in response to pressure differentials resulting from suction;

(iii) an inflation-deflation lumen having a distal end communicating with said intragastric balloon portion, and a proximal end adapted both to communicate with a source of balloon inflation fluid and to retain said fluid in said balloon, and, thereafter, to provide means for egress of said fluid during removal of said gastrostomy tube;

(iv) a substantially elongated feeding lumen in said gastrostomy tube, said feeding lumen having inlet and outlet openings positioned at proximal and distal portions, respectively, of said gastrostomy tube; and

(v) an annular elastomeric sleeve means affixed to said gastrostomy tube, in trailing relationship to said intragastric balloon portion, said annular elastomeric sleeve means adapted to contact the abdominal walls where said gastrostomy tube is surgically inserted, and said sleeve constructed of material which induces the formation by the patient'"'"'s body of a protective fibrotic sheath in the area of said contact; and

(B) an elongated, flexible intraduodenal feeding tube adapted to be inserted through said feeding lumen of said gastrostomy tube, said feeding tube having an open, distal, fluid-delivery portion adapted to communicate with the small intestine of the patient, an intermediate portion adapted to be positioned within said gastrostomy tube feeding lumen, and a proximal, fluid-receiving portion, for communicating with a source of nutrient supply.
